Make sure to set the mouse up completely before trying to play or use it day to day. You need to get the Synapse app and you need to create a surface profile for your mouse otherwise you could run in to it acting weirdly even in Windows.
I definitely feel like I've never been more competitive in FPS gaming in my life than with using this mouse. I run it at 12,500DPI and 8khz, at these settings I feel like it tracks so well it nearly predicts where my hand is going to go, it's that good.
so far, it's been about 2 weeks. this mouse is ultra light to me coming from a steelseries rival 600. the steelseries was slightly over 100 grams so it's almost 30 gram difference. this weighing in at 74. I didn't really expect it to affect my or even be noticeable. boy was I wrong. instantly lighter and the feet on this mouse glide so smoothly.
very responsive and quick. thought I may have to turn down my dpi or sens due to how much lighter and smoother the razer is. However, from that heavier steelseries with weaker glide, to this much lighter exponentially better gliding 8k, it was seamless. adjusted extremely quickly.
The shape is great feels great in my hand. did take me a minute to get used to as far as that goes simply because my last mouse was bulky and an unorthodox shape compared to most gaming mice. Now due to that there was some weird stress, and fatigue that presented in my forearm. again it adjusted quickly. after, at max, a couple 3-4 hour sessions it was gone. There are 4 total side buttons, but theres a caveat there I'll touch on later.
the wire on this is absolutely perfect. 0 drag, dont even notice it's there until I look down. dont have to use my cord bungee either. I almost got the viper ult but knowing how this mouse feels, it would've been a waste of money to me.
As great as this mouse is there are a couple trade offs and things I didnt know. these are not in number of importance.
1) since this is ambidextrous, theres 4 total side buttons, one set on each side. Coming from a mouse with 3 side buttons and the way I had things mapped, I assumed I would be able to map all 4 buttons. wrong. the buttons are M4/M5 on each side. you have to choose if you are right or left handed in the app and that sets which side is being used and how they're numbered. kind of a bummer here but this is a personal issue not necessarily reflective of razer. coming from more to less is situational. I would just like that extra personalization.
2) The 8k polling rate. this provides an extremely smooth mouse movement. this may be different from person to person. maybe mouse pads make a huge difference I have a relatively cheap one atm. One issue I've run into is Apex legends WILL NOT run a polling rate over 2000 on a 144 hz monitor. or at least not on mine. rainbow six siege I can crank to 8k and no issues. so maybe its game/display/system dependent I dont have a way to test it.
3) I'm a person who enjoys rgb and wish there was more. this is a non issue for most I'm sure, but this is about the only thing the steelseries had over this mouse was the customization options for rgb.
4) the liftoff distance. this is the number one win for steelseries. they had a liftoff distance as low as .5 mm lift off distance which I absolutely loved. the lowest for this mouse is 2 mm. so lifting and lowering there is mouse jottering I'm not a fan of but overall not a big issue. big win for steelseries here.
Barring any huge issues this is a mouse I would 100 percent recommend at time of this review. buy it, check it out. I doubt you'll be disappointed!

Es muy ligero, su peso es casi imperceptible, su manejo es notablemente mejor que cualquier otro raton que eh tenido.
Como todo lo razer, viene en su elegante caja con calcomanías, su bolso de tela e instructivo.
Completamente recomendable este producto.
***El unico detalle es que el repartidor no comunicó su llegada,lo avento a la puerta y se fue sin avisar, lo cual es desagradable ya que puede dañarse o en mi caso que tengo perros, ellos pudieron dañarlo. Únicamente por que estuve pendiente de la pagina fue que supe que el paquete llegó. Seguramente fue un repartidor externo y eso habla muy mal de Amazon... En fin.

Igual cuando conecte el mouse a mi Pc se sentía un poco como fluido pero a ala vez algo lento pero eso era por los 8khz que trae el mouse, después con la app de Razer lo puse a 1000 hz y se solucionó y va como un mouse normal y no he tenido lag en los juegos, ya que algunas personas han comentado eso.
Espero este mouse no genere algún doble click ya que ese problema generó mi Logitech que tenía y espero no pase eso. El producto es 100% original y viene con las calcomanías características de Razer y los papelitos por defecto de bienvenida e instructivo.
